 ABC News, I'm Michelle Franzen. President Biden back on the campaign trail after last night's debate against Donald Trump. The president raising concerns about his age after stumbling while answering questions. His campaign says due to a cold. Today at a rally in Raleigh, North Carolina, the president acknowledged he's not a young man, but says he can tell the truth and win. I'm here in North Carolina for one reason. Because I intend to win this state in November. You're going to see that happening.
